BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to a document production system and the like for providing easy production of a document with an illustration or vignette.

2. Related Art of the Invention

Recently, home fax machines have spring into wide use to increase fax communications for purposes other than business. In addition, personal computers and PDAs(portable digital assistance) facilitate transmission or reception of fax data. These devices permit documents produced by users to be readily transmitted to others. However, handwritten documents without illustration or documents containing only text produced by means of the personal computer or the like are prosaic and dull, far from grabbing someone's attention. Hence, a demand exists for a technique of permitting a simple operation to add illustrations or the like to the documents.

An image production system offering such a technique has been proposed in Japanese Unexamined Patent Publication No. 6(1994)-54165. This system includes, as shown in FIG. 38, an image data input section 201 for optically reading an image of a manuscript, a paint menu setting section 202 for setting a type and the like of an image to be superimposed, a paint address setting section 203 for specifying a position of the image to be superimposed, a data synthesizing section 204 for combining the manuscript image and the image to be superimposed, and an image output section 205 for outputting a composite image.

With such an arrangement, the image production system permits a user to select a suitable image, such as an illustration, and to specify a position of the image to be combined with the manuscript image read by a scanner or the like, so as to superimpose the illustration and the manuscript image on the specified places for outputting the resultant composite image.

In the image production system of Japanese Unexamined Patent Publication No. 6-54165, however, the user is responsible for all the process of selecting the image to be superimposed, such as an illustration, and specifying the layout of the document, thus going through all the cumbersome operations. Hence, it is not easy for everyone to produce a document with an illustration added thereto.

Hence, a demand exists for a document production method and system which require the user of substantially no operation for producing documents wherein illustrations are added to inputted manuscript. There also exists a need for an effective inference scheme for accomplishing such intellectual and complicated operations.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

Now the preferred embodiments of the invention will hereinbelow be described with reference to the accompanying drawings.

First Embodiment

FIG. 1 is a block diagram showing an arrangement of an image production method and system according to a first embodiment of the invention. Referring to the figure, the system includes image input means 1 for inputting an image; image decoding means 2 for expanding the image data inputted by the image input means into a bitmap image; descriptive region detecting means 3 for detecting only an image of a descriptive region exclusive of a background portion of the bitmap image generated by the image decoding means 2; input-image dividing means 4 for dividing the input image in a grid form; in-grid pixel counting means 5 for counting a number of pixels included in one grid portion and forming an image of a different color from the background image; rectangular region generating means 6 for detecting, as the descriptive region image, a rectangular region including all grid portions in which a count of pixels exceeds a threshold value; image characteristic value calculating means 7 for calculating, as image characteristic values, a horizontal length, a vertical length, a mean pixel luminance and a luminance distribution of the descriptive region image detected by the descriptive region detecting means; descriptive region segmenting means 8 for segmenting the descriptive region image into at least two segments; in-segmental-descriptive-region-image pixel counting means 9 for counting a number of pixels of each segmental region, which pixels form an image of a color different from the background image; layout pattern storage means 10 for storing a layout pattern of a manuscript; table storage means 11 for storing a table used for deciding a manuscript layout; layout pattern selecting means 12 for selecting a layout pattern of the manuscript; illustration storage means 13 for storing illustration data; illustration selecting means 14 for selecting an illustration; document producing means 15 serving to combine the selected layout pattern, the selected illustration and the descriptive region image together for production of the document; image encoding means 16 for encoding the bitmap image of the produced document into a form for storage or output; and document output means 17 for outputting an image of the encoded document.

The input-image dividing means 4, in-grid pixel counting means 5 and rectangular region generating means 6 constitute the descriptive region detecting means 3. The descriptive region segmenting means 8 and in-segmental-descriptive-region-image pixel counting means 9 constitute the image characteristic value calculating means 7.

FIG. 2 diagrammatically illustrates a hardware construction for carrying out the system of the above arrangement.

The construction of FIG. 2 is essentially the same with that of the general-purpose computer system. In addition, this construction includes identical components to those of the system arrangement of FIG. 1. Therefore, such components are represented by like reference numerals and the description thereof is omitted.

Referring to FIG. 2, the construction includes the image input means 1, the document output means 17, a VRAM 101 for storing data to be displayed/outputted, a main storage 102 composed of a volatile memory for storing a program, an auxiliary storage 103 composed of a nonvolatile memory for storing a program and data, a CPU 104 for executing the program stored in the main storage 102, a scanner 105 for optically reading the manuscript, and a printer 106 for printing the outputted document.

As described above, the hardware is essentially constructed the same way as the computer system wherein the program stored in the auxiliary storage 103 is loaded into the main storage 102 and then executed by the CPU 104.

The image production method and operations of the system arranged as described above will be described with reference to the flow chart shown in FIG. 3.

(STEP A1)

First, the manuscript image read by the scanner 105 is inputted in the image input means 1. It is hereinafter assumed that the input image has a white background and a size of A4. As shown in FIG. 4, a text and the like are written on the A4 sheet.

(STEP A2)

The image decoding means 2 serves to decode the image inputted at STEP A1 into a bitmap image. In the case of an A4 manuscript image inputted at a resolution of 100 DPI (dot per inch), the bitmap image has a horizontal length of 864 dots and a vertical length of 1080 dots. It is assumed hereinafter that the image is of a white/black binary image in which a white pixel is represented by 0 and a black pixel is represented by 1.

The input image dividing means 4 divides the image decoded at STEP A2 into a grid form as shown in FIG. 5. If a grid portion is in a size of 32 (horizontal)×30 (vertical) dots, the 864×1080 dot image is divided into a 27 (horizontal)×36 (vertical) grid array.

(STEPs A4 to A7)

The in-grid pixel counting means 5 counts a number of pixels included in one grid portion and representing a different color from the background. In this example, a number of black pixels is counted because the background color is white. Then, if the number of black pixels in a grid portion exceeds a predetermined threshold value, the grid portion is flagged. This operation is performed on all of the grid portions. FIG. 6 shows the flagged grid portions in the form of solid black squares.

(STEP A8)

The rectangular region generating means 6 defines a minimum size of rectangular region that includes all the grid portions flagged through the operations of STEPs A4 to A7, as an image of a descriptive region 50 of the input manuscript image. The operation of STEP A5 prevents the defined descriptive region image 50 from including black pixels resulting from fine noises. It is to be noted that such a rectangular region is not limited to one but may exist in plural numbers.

FIG. 7 shows the image of the descriptive region thus defined.

(STEP A9)

The descriptive region segmenting means 8 segments the descriptive region image detected by the descriptive region detecting means 3 into four segments, as shown in FIG. 8.

(STEP A10)

In this step, there is counted a number of pixels included in each of the segmental descriptive region images defined at STEP A9 and representing a different color from the background. That is, a number of black pixels is counted here. Subsequently, the pixel count for each segmental descriptive region image is normalized based on a total number of pixels of the segmental descriptive region image.

If, for example, a descriptive region image detected at STEP A8 has a size of 300 (horizontal)×300 (vertical) dots, the descriptive region image is divided into four segmental descriptive regions at STEP A9, one of which segmental descriptive regions has a size of 150 (horizontal)×150 (vertical) dots. If, in this case, a certain segmental descriptive region image presents a black pixel count of 10000, the pixel count is normalized by the total number of pixels of the segmental descriptive region image (150×150=22500). Thus, the normalized black pixel count of this segmental descriptive region image is 10000/22500=0.44.

Each of the segmental regions is subject to this operation thereby to give a luminance distribution of the descriptive region image. Additionally, a mean pixel luminance is found from a ratio of the black pixel count versus the white pixel count.

(STEP A11)

The layout pattern selecting means 12 selects a layout pattern by referring, to the table stored in the table storage means 11, the horizontal and vertical lengths of the manuscript descriptive region image detected at STEP A8 and the normalized black pixel count and the mean luminance obtained at STEP A11. First, the horizontal and vertical lengths, black pixel count and luminance, which are continuous values, are classified into three categories of great″, medium″ and small″ based on value range. By way of example of the horizontal length of the descriptive region image, a horizontal length of 600 or more dots is regarded as great″, that of less than 600 dots and not less than 300 dots is regarded as medium″, and that of less than 300 dots is regarded as small″. Further by way of example of the black pixel count, a count of not less than 0.7 is regarded as great″, that of less than 0.7 and not less than 0.4 is regarded as medium″, and that of less than 0.4 is regarded as small″.

Subsequently, the parameters thus defined are referred to the table (Table 1) for selection of the layout pattern.

TABLE 1 IMAGE CHARACTERISTIC VALUE BLACK BLACK BLACK BLACK PIXEL PIXEL PIXEL PIXEL MEAN HORIZONTAL VERTICAL COUNT FOR COUNT FOR COUNT FOR COUNT FOR LUMINANCE LENGTH OF LENGTH OF SEGMENTAL SEGMENTAL SEGMENTAL SEGMENTAL OF DESCRIP- DESCRIP- DESCRIP- DESCRIP- DESCRIP- DESCRIP- DESCRIP- TIVE TIVE TIVE TIVE TIVE TIVE TIVE LAYOUT REGION REGION REGION 1 REGION 2 REGION 3 REGION 4 REGION PATTERN GREAT GREAT GREAT GREAT GREAT GREAT GREAT 2 GREAT GREAT GREAT GREAT GREAT GREAT MEDIUM 5 . . . . . . . . . . . . . . . . . . . . . . . . GREAT MEDIUM MEDIUM SMALL SMALL SMALL MEDIUM 7 . . . . . . . . . . . . . . . . . . . . . . . .

In a case where, for example, a descriptive region image 50 has the great horizontal length and the medium vertical length, the segmental descriptive region images have pixel counts of medium, small, small and small, respectively, and the mean luminance is medium, a seventh layout pattern is selected from Table 1. A relation of the parameters of the descriptive region image, such as great, medium and small, versus the layout pattern to be selected is previously determined by statistical processing of questionnaire answers from designers. The statistical processing is directed to the overall balance of the document layout and the reduced transmission amount.

The layout pattern is stored in the layout pattern storage means 10 in the form of description on a number of illustrations and positions of illustrations and the descriptive region image, as shown in FIG. 9.

FIG. 9 a depicts an imaginary layout pattern thus specified. In actual practice, however, the same content as that of FIG. 9 a is expressed by a list of numbers of illustrations and coordinate information pieces, as shown in FIG. 9 b.

(STEP A12)

The illustration selecting means 14 selects from the illustrations stored in the illustration storage means 13 an illustration to be inserted in a superimposition area of the layout pattern selected at STEP A11. The illustration is selected based on, for example, random numbers.

(STEP A13)

The illustration selected at STEP A12 and the image 50 of the manuscript descriptive region are superimposed on the layout pattern selected at STEP A11.

The descriptive region image is superimposed on the layout pattern of FIG. 9 at the position of the descriptive region. It is to be noted here that the layout pattern selected from the table at STEP A11 includes the descriptive region superimposition area, which has a size equal to or greater than the read descriptive region image. Accordingly, the descriptive region image is laid at the center of the descriptive region superimposition area when the descriptive region image is combined with the layout pattern. In order to permit this, there may be prepared such a layout pattern as to accommodate a rectangular region of a maximum size.

(STEP A14)

The text image of the descriptive region of the input manuscript is superimposed on the layout pattern to produce a composite image, which is encoded into a form for output.

(STEP A15)

The encoded image is applied to the image output means 17 so as to be printed by the printer 106.

FIG. 10 shows an exemplary output of a document thus produced.

The aforementioned sequence of document production operations automatically detect the descriptive region of the manuscript and add the illustration thereto based on only limited necessary items entered to the manuscript by the user. Furthermore, the operations determine the positions of the respective images of the illustration and the manuscript descriptive region according to a state of the descriptive region image, thereby accomplishing the layout in which the images of the illustration and descriptive region are laid in balance.

Although the first embodiment of the invention has been described by way of example of the black/white binary image of A4 size, it should be understood that the invention is not limited in the manuscript size, the number of colors and the like and may be embodied in an optional size and number of colors.

In addition to the predetermined position to lay the illustration, the layout pattern may include a predetermined illustration. In this case, the layout pattern includes both the content (e.g., sparrow) and the position of the specific illustration, as shown in FIG. 11. Incidentally, the illustration selecting means 14 may be omitted.

Although the first embodiment hereof uses the horizontal and vertical lengths, black pixel count and mean luminance of the descriptive region image of the manuscript for deciding the document layout, it is to be understood that the invention should not be limited to the above. A similar effect may be attained by using any other image characteristic values obtained from the descriptive region image.

According to the first embodiment hereof, there is one type of document produced. An alternative arrangement may be made such that plural types of optional documents are displayed on a monitor screen (not shown) for allowing the user to select one from these.

According to the first embodiment hereof, the manuscript image is read by the scanner 105. Alternatively, a key board 107 and a font image generating means 108 may be provided, as shown in FIG. 12, such that a text entered by the user through the key board 107 is converted into an image by the font image generating means 108 and the converted image is inputted in the image input means 1. This arrangement also permits the production of the document wherein the illustration is automatically added to the text entered by the user.

According to the first embodiment hereof, the manuscript image is read by the scanner 105. Alternatively, a data modem 109 may be connected to a facsimile 110 via a telephone line, as shown in FIG. 13, for inputting the manuscript image through the facsimile 110. This arrangement also permits the production of the document with the illustration automatically added thereto.

According to the first embodiment hereof, the printer 106 is employed for printing the produced document image. Alternatively, the data modem 109 is connected to the facsimile 110 via the telephone line, as shown in FIG. 14, such that the outputted document is transmitted to the facsimile 110 via the data modem 109. This arrangement also permits the printing of the document with the illustration added thereto.

According to the first embodiment hereof, the illustration selecting means 14 serves to select a specific illustration based on random number. Alternatively, the user himself may select a specific illustration and superimpose the selected illustration on an illustration insertion area. In this case, optional illustrations are displayed by means of illustration display means (not shown) for allowing the user to select a desired illustration through input means such as the key board.

Second Embodiment

FIG. 15 is a block diagram showing an arrangement of an image production method and system according to a second embodiment of the invention.

The arrangement of FIG. 15 includes identical components to those of the system arrangement according to the first embodiment hereof. Therefore, such components are represented by like reference numerals and the detailed description thereof is omitted.

The system of the second embodiment hereof includes the image input means 1, the image decoding means 2, the descriptive region detecting means 3, the input-image dividing means 4, the in-grid pixel counting means 5, the rectangular region generating means 6, the image characteristic value calculating means 7, the descriptive region segmenting means 8, the in-segmental-descriptive-region-image pixel counting means 9, the layout pattern storage means 10, rule storage means 18 for storing fuzzy rules used for the layout decision, fuzzy inference means 19 a for performing inference based on the fuzzy rules stored in the rule storage means thereby deciding the layout pattern, defuzzificating means 25 for finding a real value from a fuzzy inference result, the layout pattern selecting means 12, the illustration storage means 13, the illustration selecting means 14, the document producing means 15, the image encoding means 16 and the document output means 17.

A hardware construction for carrying out the system of the above arrangement is essentially the same with the general-purpose computer system and is shown in FIG. 2. Since this arrangement is the same as the construction of the first embodiment hereof, the description thereof is omitted.

The image production method and operations of the image production system of the above arrangement will be described with reference to the flow, chart shown in FIG. 16.

(STEPs B1 to B10)

Operations at these steps are the same as those performed at STEPs A1 to A10 shown in FIG. 3 and therefore, the description thereof is omitted.

(STEPs B11 to B13)

A layout pattern is selected by applying a horizontal and a vertical length of a manuscript descriptive region image detected at STEP A8 and a normalized black pixel count and a mean luminance determined at STEP B10 to the rules.

The rules for layout pattern selection are stated according to the fuzzy rules, as shown in FIG. 17.

For example, as to the case of a descriptive region image 50 with the great″ horizontal length, each layout pattern is described according to the fuzzy rules, indicating a degree of favorableness of the layout pattern. Likewise, as to the cases of descriptive region images with the medium″ and small″ horizontal lengths, the description is made on each layout pattern, indicating a degree of favorableness thereof.

As to the other attributes or the vertical length, black pixel count, mean luminance of the descriptive region image 50, a relation between each of the attribute values and each layout pattern is stated according to the fuzzy rules. Such fuzzy rules are stored in the rule storage means 18.

Now, the description will hereinbelow be made on how the layout pattern is selected by using the fuzzy rules. For simplicity, the description will be made by way of example of an inference operation using the horizontal length of the descriptive region image alone.

First at STEP B11, in the case of a descriptive region image 50 with the horizontal length of 500 dots, the fuzzy inference means 19 a ignites rules for the great″ and medium″ descriptive region images 50 for truncating a membership function of the favorableness of each layout pattern, as the consequent part, based on a membership function of the antecedent part.

FIG. 18 a illustrates the process of this operation.

As to the great″ and medium″ descriptive regions thus truncated, the membership functions of the consequent parts are OR-synthesized to give an inference result.

FIG. 18 b shows the inference result indicating a degree of favorableness of each layout pattern.

At the subsequent STEP B12, the defuzzificating means 25 defuzzificates the inference results by determining respective centroids thereof.

FIG. 18 c illustrates a process of obtaining real values through the defuzzification procedure. The procedure gives the degree of favorableness of each layout pattern in terms of real value.

At the subsequent STEP B13, the layout pattern selecting means 12 selects one from the layout patterns that has the greatest real value of favorableness determined at STEP B12.

The fuzzy inference actually includes similar fuzzy rules for the other attribute values in addition to that for the horizontal length of the descriptive region image. Therefore, inference results based on the other rules are OR-synthesized to give a synthetic fuzzy inference result. The fuzzy rules used herein are formulated based on statistical data obtained from a questionnaire to designers and the like.

(STEPs B14 to B17)

Operations at these steps are the same as those performed at STEPs A12 to A15 shown in FIG. 3 and therefore, the description thereof is omitted.

The aforementioned sequence of document production operations automatically detect the descriptive region of the manuscript and add the illustration thereto based on only limited necessary items entered to the manuscript by the user. Furthermore, the operations determine the positions of the respective images of the illustration and the manuscript descriptive region according to the state of the descriptive region image, thereby accomplishing the layout in which the images of the illustration and descriptive region are laid in balance.

Although this embodiment hereof has been described by way of example of the black/white binary image of A4 size, it should be understood that the invention is not limited in the manuscript size, the number of colors and the like and may be embodied in an optional size and number of colors.

In addition to the predetermined position to superimpose the illustration, the layout pattern may include a predetermined illustration.

In the fuzzy inference operation according to the second embodiment hereof, the consequent parts are OR-synthesized but may be synthesized by any other method. Further, the inference results are defuzzificated by determining the centroids thereof but may be defuzzificated by any other method.

Although this embodiment hereof uses the fuzzy inference operation for deciding the layout pattern, an inference operation based on the typical if—then rules rather than on the fuzzy logic, or any other inference operation may be used. In this case, the rule storage-means 18 shown in FIG. 15 contains general statements of the production rules, neural net, clustering procedure and the like, instead of the fuzzy rules. Further, the fuzzy inference means 19 a and the defuzzificating means 25 are replaced by inference means 19. Hence, a system in this case is arranged the same way as shown in FIG. 19.

The arrangement of FIG. 20 includes identical. components to those of the system arrangement according to the second embodiment hereof. Therefore, such components are represented by like reference numerals and the detailed description thereof is omitted.

The system of the third embodiment hereof includes the image input means 1, the image decoding means 2, the descriptive region detecting means 3, the input-image dividing means 4, the in-grid pixel counting means 5, the rectangular region generating means 6, the image characteristic value calculating means 7, the descriptive region segmenting means 8, the in-segmental-descriptive-region-image pixel counting means 9, the layout pattern storage means 10, the rule storage means 18, the fuzzy inference means 19 a, the defuzzificating means 25, clustering means 26 for clustering the fuzzy inference results, the layout pattern selecting means 12, the illustration storage means 13, the illustration selecting means 14, the document producing means 15, the image encoding means 16 and the document output means 17.

A hardware construction for carrying out the system of the above arrangement is essentially the same as the general-purpose computer system and is shown in FIG. 2. Since this arrangement is the same with the construction of the first embodiment hereof, the description thereof is omitted.

The image production method and operations of the system of the above arrangement will be described with reference to the flow chart shown in FIG. 21.

(STEPs C1 to C10)

Operations at these steps are the same as those performed at STEPs A1 to A10 shown in FIG. 3 and therefore, the description thereof is omitted.

(STEPs C11 to C14)

A layout pattern is selected by applying a horizontal and a vertical length of the manuscript descriptive region image detected at STEP C8 and a normalized black pixel count and a mean luminance determined at STEP C10 to the rules.

As shown in FIG. 17, the rules for layout pattern selection are stated according to the fuzzy rules similarly to the second embodiment hereof.

Now, how the fuzzy rules are used to select the layout pattern will be described. For simplicity, the description will be may by way of example of an inference operation using the horizontal length of the descriptive region image alone.

At STEP C11, the fuzzy inference is performed on the horizontal length of the descriptive region image 50. This inference operation takes the same procedure as in STEP B11 according to the second embodiment hereof.

FIG. 22 a show the process of this inference operation.

FIG. 22 b shows favorablenesses of the respective layout patterns thus obtained as the inference results.

Referring to FIG. 22 b, the inference result includes two regions indicative of the favorableness of the layout pattern 1. This is ascribable to the consequent part of a rule shown in FIG. 22 a which includes two membership function peaks indicating the favorableness of the great″ horizontal length.

The fuzzy rule with such a characteristic may be obtained when the fuzzy rules are formulated based on the questionnaire. More specifically, such a rule may be formulated when some answers are favorable″ while the others are unfavorable″ as to the great″ horizontal length of the layout pattern 1.

On the other hand, the inference result of the layout pattern 2 presents such a shape as observed in the typical fuzzy inference operation, or presenting only one region.

Here, the inference result of FIG. 22 b is defuzzificated simply by finding a centroid of the region. Hence, the favorableness of the layout pattern. 2 is defuzzificated in the proximity of 0.5.

Actually, however, the favorableness is sharply divided about the layout pattern 1. Thus, an appropriate inference result seems to be obtained by discretely defuzzificating the two regions for finding two values thereof, rather than defuzzificating both the regions together for obtaining an intermediate value of 0.5, the two regions representing a positive subjectiveness and a negative subjectiveness, respectively.

Hence, the inference results are subject to a clustering procedure at STEP C12, thereby to determine how many output values are obtained. Any method may be used for the clustering procedure. This embodiment takes the clustering procedure based on the well-known fuzzy c-means method (Literature 1:Bezdek: “Pattern Recognition with Fuzzy Objective Function Algorithm”, Plenum Press, 1982 incorporated herein by reference).

The clustering procedure based on the Fuzzy C-Means Method is initiated at a number of cluster unit of 1 for finding Bezdek-s evaluation value Jc(C=1) with respect to cluster unit number 1. Subsequently, the operation proceeds with the number of cluster unit increased by 1 at a time. At each increase in the number of cluster unit, the evaluation value Jc is found based on equation 1. J _(c) −J _(c−1)>δ_(J)  EQUATION 1

When these evaluation values satisfy equation 1 with respect to a certain threshold value δj, the clustering procedure is completed to give an evaluation value C, which indicates the number of inference values to be outputted.

According to this clustering procedure, the inference result of the layout pattern 1 presents two cluster units while the inference result of the layout pattern 2, presents one cluster unit, as shown in FIG. 22 b.

At the subsequent STEP C13, the defuzzificating means 25 defuzzificates the result by determining the centroid thereof.

FIG. 22 c illustrates a process of obtaining the real values through the defuzzification procedure. The aforementioned procedure provides the degree of favorableness of each layout pattern in terms of real value. That is, there are obtained two real values with respect to the layout pattern 1 and one real value with respect to the layout pattern 2.

At the subsequent STEP C14, the layout pattern selecting means 12 selects one from the layout patterns that has the greatest real value of favorableness determined at STEP C13. It is to be noted that a rule for a layout pattern presenting not less than two real values is previously set such that, for example, the selection is always determined based on the greatest value. An alternative rule may be made such that a layout pattern with the lowest value is not selected.

In actual practice, the fuzzy inference also observes similar rules for the other attribute values besides the horizontal length of the descriptive region image. Accordingly, the synthetic fuzzy inference result is obtained by OR-synthesizing the inference results based on the other rules. The fuzzy rules used herein are formulated based on the questionnaire to the designers and the like.

Operations at these steps are the same as those performed at STEPs A12 to A15 shown in FIG. 3 and therefore, the description thereof is omitted.

(STEPs D1 to D10)

Operations at these steps are the same as those performed at STEPs A12 to A15 shown in FIG. 3 and therefore, the description thereof is omitted.

(STEP D11)

A schematic layout pattern is selected by applying a horizontal and a vertical length of the manuscript descriptive region image detected at STEP D8 and a normalized black pixel count and a mean luminance determined at STEP D10 to the rules. First, the horizontal and vertical lengths, black pixel count and mean luminance, which are continuous values, are classified into three categories of great″, medium″ and small″ based on value range. The classification method is the same as the aforementioned operation at STEP A11 of the first embodiment hereof.

Subsequent to this classification operation, reference is made to the table (Table 2) for selection of a schematic layout pattern.

TABLE 2 IMAGE CHARACTERISTIC VALUE BLACK BLACK BLACK BLACK PIXEL PIXEL PIXEL PIXEL MEAN HORIZONTAL VERTICAL COUNT FOR COUNT FOR COUNT FOR COUNT FOR LUMINANCE LENGTH OF LENGTH OF SEGMENTAL SEGMENTAL SEGMENTAL SEGMENTAL OF DESCRIP- DESCRIP- DESCRIP- DESCRIP- DESCRIP- DESCRIP- DESCRIP- SCHEMATIC TIVE TIVE TIVE TIVE TIVE TIVE TIVE LAYOUT REGION REGION REGION 1 REGION 2 REGION 3 REGION 4 REGION PATTERN GREAT GREAT GREAT GREAT GREAT GREAT GREAT 1 GREAT GREAT GREAT GREAT GREAT GREAT MEDIUM 9 . . . . . . . . . . . . . . . . . . . . . . . . SMALL GREAT MEDIUM SMALL SMALL SMALL MEDIUM 4 . . . . . . . . . . . . . . . . . . . . . . . .

In a case where a descriptive region image has the small horizontal length and the great vertical length, segmental descriptive regions have pixel counts of medium, small, small and small in this order, and the mean luminance is medium, for example, a schematic layout pattern 4 is selected from Table 2.

The schematic layout pattern storage means 20 stores the schematic layout pattern in which the number of illustrations, the approximate positions of the illustrations and the position of descriptive region image are described, as shown in FIG. 25 a.

In actual practice, allowable ranges of the number of illustrations and the illustration positions are described, as shown in FIG. 25 b.

(STEP D12)

The layout fine adjustment means 21 performs fine adjustment of a layout based on the schematic layout pattern selected at STEP D11 and the aforesaid image characteristic values.

The layout fine adjustment is performed by using the table for layout fine adjustment shown in Table 3, which is stored in the table storage means 11 b.

TABLE 3 IMAGE CHARACTERISTIC VALUE HORIZONTAL VERTICAL SCHEMATIC LENGTH OF LENGTH OF LAYOUT DESCRIPTIVE DESCRIPTIVE POSITION OF PATTERN REGION REGION ILLUSTRATION 4 GREAT GREAT ILLUSTRATION 1 x = 60, y = 100 ILLUSTRATION 2 x = 160, y = 100 4 GREAT MEDIUM ILLUSTRATION 1 x = 70, y = 110 ILLUSTRATION 2 x = 170, y = 110 . . . . . . . . . . . . 4 SMALL GREAT ILLUSTRATION 1 x = 50, y = 90 ILLUSTRATION 2 x = 150, Y = 90

This table gives coordinates of a position of an illustration associated with, for example, a schematic layout pattern 4 in which the descriptive region image has the small″ vertical length and the great″ horizontal length. This operation provides varied layouts from one selected schematic layout pattern, the layouts varied depending upon a state of the descriptive region image as shown in FIG. 26. Although not shown in Table 3, the descriptive region has an allowance of the position thereof, as shown in FIG. 25 b, thus allowing for the fine adjustment.

(STEPs D13 to D16)

Furthermore, as compared to a document of a similar layout which is not subject to the fine adjustment, a document with better appearance may be obtained by having the layout thereof fine adjusted according to the state of the manuscript descriptive region image.

According to the fourth embodiment hereof, the selection of the schematic layout pattern and the fine adjustment of the layout are performed with reference to the tables. Instead of relying on the tables, the decision of the schematic layout pattern and the layout fine adjustment may be accomplished by performing the rule-based inference, the fuzzy inference based on the fuzzy rules or the fuzzy inference for obtaining plural outputs through the clustering procedure.
